How to install Spyder Python without Anaconda in Windows 10 correctly | {Spyder 4.2.3}

This spyder python tutorial will teach you "How to install Spyder Python in Windows without Anaconda. As a matter of fact, Spyder is already part of Anaconda packages. So, if you have installed Anaconda in your system, then you will have Spyder also. But what if, you want to install Spyder independently? Because You know installing Anaconda may conflict with your other already installed software or packages. So no worries on this part anymore. Spyder provides standalone installers to achieve that.

I will use Spyder and Spyder Python terms. Please don't get confused with the interchanging of these terms. Spyder comes with Python by default. So sometimes, people refer to it as Spyder Python. Always remember, Spyder made in Python and made for Python (Scientific) programming.

Let's checkout some quick details about Spyder Python first.

What is Spyder Python?

The Spyder stands for "Scientific PYthon Development EnviRonment". Spyder is an open-source python-based Integrated development environment (IDE) for scientific programming. Pierre Raybaut developed Spyder in 2009 and later community and scientific developer team maintained and improved it. Spyder uses cute (QT) for it's GUI and designed to use either of the PyQt or PySide Python bindings. It provides enhanced editing, debugging, awesome visualization and interactive testing to developers.

Features of Spyder Python -

  • Advance editor for code completion, syntax highlighting and introspection
  • Edit variables from GUI also
  • Code benchmarking can be done using a run-time profiler
  • Inbuilt file explorer to manage the filesystem

Reloaded-modules-spyder
  • Go to Tools -> Preferences -> Python Interpreter > User Module Reloader.
